The samples were extracted with methyl alcohol, pttrified, analyzed by high performance liquid chromatography, and quantified with external standard method. The results showed a good linear correlation within the concentration range of 250 - 2 000 μg/ml, and the correlation coefficient was 0. 999 6. The standard recovery rate ranged from 97% to 109%, and the relative standard deviation was lower than 2.4%. Furthermore, phosphatidylcholine contents ~f Z. mor/o individuals at different growth stages were determined. According to the results, the variation pattern of phosphatidylcholine contents of Z. mor/o with individual weight was consistent with the binomial curve, and the correlation coefficient was R^2=0. 865 （P 〈0.01 ）. This study laid methodological foundation for the development of Z. mor/o functional products.展开更多

This process gives off EPS microplastics, which can find their way into water, food, blood, and major organ systems. Zophobas morio larvae are capable of consuming and breaking down EPS within their digestive tracts by minimizing the spread of microplastics. Studies of the consumption of EPS by Z. morio larvae are typically conducted under white or no visible light treatments. This study tested whether the color of visible light influenced the consumption rate of EPS by Z. morio larvae. If Z. morio larvae consume EPS under visible light, then visible light will influence the amount of EPS consumed. If results suggest that the consumption rate is influenced by visible light colors, then Z. morio larvae could be a solution for recycling EPS. This study’s procedure placed Z. morio larvae into 25 jars under one of six visible light treatments of red, yellow, green, blue, white, and no visible light. Each jar contained a pre-weighed block of EPS and six Z. morio larvae. After two weeks, the Z. morio larvae were removed from the jars, and the difference between each pre-weighed EPS block and the weight of the same partially consumed block was recorded in three trials. The data indicates that green and blue visible light treatments resulted in the greatest amount of EPS consumed by Z. morio larvae while the red and yellow had the least amount of EPS consumed by the Z. morio larvae. In conclusion, results indicate that green and blue visible light, compared to the no visible light treatment, could be used to influence the Z. morio larvae to consume more EPS. Green and blue visible light and Z. morio larvae could make the recycling process of EPS more environmentally friendly when used in households or by local environmental organizations.展开更多
